  • US 2010/0092767 A1 discloses a bonding method which includes applying a liquid material containing silicone materials to at least one of the first base member and the second base member so as to form a liquid film, drying the liquid film so as to obtain a bonding film on the at least one of the first base member and the second base member, heating the bonding film so as to cross-link the silicone materials contained in the bonding film to each other, and applying energy to the bonding film so as to develop adhesiveness around a surface of the bonding film so as to obtain a bonded body in which the first base member and the second base member are bonded to each other with the bonding film interposed between the first base member and the second base member.
  • JPH01293334 A discloses a method of minimising warping and to preventing the deterioration of resolution and by providing a transparent elastic body between a light diffusing plate and translucent plate.
  • the transparent elastic body is provided between the light diffusing plate and translucent plate.
  • the total thickness of the light diffusing plate and translucent plate suffices for mechanical strength; even if a variation of tolerance arises between the light diffusing plate and translucent plate due to changes in temperature and humidity.
  • the elastic body is easily deformed depending on the variation of the tolerance, so that warping of the transmission type screen is greatly minimised. Since warping is minimised, the deterioration of resolution and the occurrence of contradictory feely are prevented.
  • the present invention relates to a method for manufacturing an optical component according to independent claim 1.
  • Embodiments of the present invention provide an optic formed at least partially of moldable silicone.
  • Various types of silicone materials having the properties described herein are available from Dow Corning ("Dow").
  • Dow's MS-1002 moldable silicone may be useful in certain applications.
  • other sources for moldable silicone materials are known or readily identified by those skilled in the art.
  • Such optics may be formed by a variety of methods or combinations of methods, including extrusion and casting/molding.
  • Embodiments of the methods contemplated herein use an extrusion machine to form the optic.
  • Traditional extruder systems include an extrusion machine that delivers the molten polymeric lens material (e.g., acrylic) to an extruding die and then on to a separate shaping die that imparts the final lens shape.
  • the lens material is exposed to air as it moves between the extruding die and the shaping die, which accelerates cooling and thus curing (particularly the outer surface) of the material between the extruding die and the shaping die.
  • the die tends to scrape the hardened outer surface or shell of the partially-formed optic, thereby causing undesirable striations extending along the length of the final optic.
  • Optical pattern molding may include partially or fully encapsulating a second optical component constructed from a second material such as glass or another optical material (the second optical component may be a printed circuit board or a reflector) within a silicone first optical structure through an injection mold process machine co-molding the parts together to form a single device with multiple optical structure components.
  • the resultant device can include mechanical features or structures for mounting, sealing, or may include textures or patterns to occlude the view through the mechanical structure.
  • Embodiments of the methods contemplated herein combine an extruding die and shaping die into a single optic forming device having a die or mold therein for forming the optic with the desired geometry. Embodiments of this system are shown in Figs. 1-4 .
  • the optic forming device is also provided with heating / cooling elements to cure the silicone and thereby set it in the desired shape.
  • moldable silicone may be formed from two liquid components combined to form a liquid that is heated to a curing temperature at which the silicone becomes solid.
  • the first part 210a and the second part 210b may be, for example, (1) a base and a curing agent or (2) an unpolymerized or partially polymerized resin and a crosslinking reagent. While the pre-cured viscosity of silicone can vary, in some embodiments, it has a viscosity similar to water.
  • the first and second parts 210a and 210b are moved from the extrusion machine 201 to the optic forming device 202.
  • the optic forming device may be mounted on a tool platform 203.
  • the optic forming device 202 includes an extrusion mechanism to extrude the silicone optic. After the silicone enters the optic forming device, it is extruded through a die 206. Heating elements 205 provide heat to cure the silicone. In this way, a silicone optic can be continuously extruded using the optic forming device 202 and subsequently cut into the desired lengths.
  • the optic forming device 202 includes a mold 301.
  • the liquid silicone flows into the mold, and, due to its low viscosity, it fills the mold completely leaving no gaps or shrinkage.
  • the mold 301 may include locating pins 302 and corresponding holes 303.
  • the heating elements 205 cure the silicone in the mold 301.
  • this casting process is a one shot process where the mold has the precise dimension and geometry of the desired optic. Silicone is injected into the mold through a first gate at an upstream end of the mold and is cured in the mold ( e.g., see Fig. 4 ). The mold is then opened, the optic removed, the mold closed again, and the process repeated so as to form additional, discrete optics.
  • the mold is formed by a first half mold 301a and a second half mold 301b, at least one of which is moveable relative to the other such that the two halves can be held together by a clamp 304.
  • the two half molds are separated to open the mold 301 and allow the molded part to be removed.
  • the mold 301 is then closed again and the process repeated.
  • This process can permit over-molding silicone onto other existing or previously formed components (including pre-molded or cast materials) such as glass, metals, plastics, printed circuit boards, materials with optical properties such as a reflector, or a mechanical fastener device to mount the optic in a luminaire, as discussed in more detail below.
  • This process may also be used to over mold several times to build up the desired optical distribution or properties.
  • Such features may be desirable (but not required) to control the distribution of light parallel to the length of the optic.
  • the curing process may be limited to a maximum curing temperature.
  • a silicone optic is co-molded with a second component that is temperature-sensitive.
  • a maximum curing temperature of 105°C may be established.
  • the optic forming device 202 includes a mold 401 that can produce a continuous optic that includes multiple adjacent segments which are formed sequentially. As shown in Fig. 4 , after an optic is at least partially cured in a mold 401, it may be moved longitudinally from the mold 401 so as to allow additional silicone material to fill the mold through the first gate 402 behind it for a repeated process.
  • a second gate 403 may be provided at the downstream end of the mold. After the optic is formed, the second gate 403 may be temporarily opened to permit at least a portion of the molded optic to move from the mold, after which, if necessary or desirable, the second gate 403 may be closed again (or partially closed) and the process repeated.
  • the molded optic can be moved from the mold using a variety of methods, including fluid pressure. Fluid may be injected adjacent to the first gate 402 to move the at least partially cured optic toward the second gate 403.
  • the fluid used to move the optic through the mold may be a liquid or a gas including, for example, water, air, argon gas, carbon dioxide, or any inert gas.
  • the optic can be formed having any practical length and subsequently cut to length or separated as needed to produce a part, for example, 24" (61 cm), 48" (122 cm), or 96" (244 cm) long.
  • Using fluid to propel the optic is advantageous compared to other methods known to the art such as ejector pins.
  • Ejector pins typically leave large witness lines and create images on the surface along the optic, often in several locations, which is not desirable for optical performance.
  • the fluid can be expelled from one location along the optic (unlike several ejector pins known to the art) such that the fluid creates a ripple effect along the optical surface where the fluid moves and or removes the optic from the mold.
  • the ripple effect is caused by injecting fluid at one end of the tool at the surface of the optical finish where the silicone contacts the mold.
  • This forceful injection of fluid through pneumatics or hydraulics compresses the silicone part in the mold, creating a small bubble at the interface between the surface of the mold and the silicone optic part that propagates along the part to the opposite end of the tool, causing the part to break free from the mold and begin moving to facilitate a transition to another stage of the process for additional over molding, continuous molding, or removal of the part all together from the mold.
  • the silicone is heat cured and initially forms a shell at the optic surface. Because silicone has no significant expansion/contraction differential, curing of the inner part of the optic after the outer part is cured does not distort the outer shell. Thus, it is possible to mold very complex and detailed optics with high thick to thin ratios using silicone. It is also possible to remove the silicone optic from the optic forming device before it is completely cured to increase production efficiency. Rather, the silicone can be sufficiently cured in the optic forming device to be self-supporting and then removed from the optic forming device. The partially-cured optic can be set aside or further heated to realize full cure without distorting the shape of the optic.
  • Embodiments of optics contemplated herein can include linear optics or round or otherwise discrete optics. Such optics may be formed by the processes described above or by other processes known in the art.
  • a continuous linear optic may be formed entirely of silicone.
  • the optic may be formed of any length.
  • the optic is slim in width compared to its length.
  • the optic length is between 24" (61 cm) and 96" (244 cm) long, inclusive.
  • a silicone optic may also be extruded or cast/molded onto an existing or previously formed component (including pre-molded or cast materials) such as glass, metals, plastics, printed circuit boards, materials with optical properties such as a reflector, or a mechanical fastener device to mount the optic in a luminaire.
  • Fig. 5 illustrates an optic formed by co-extruding two brackets 501, a first previously formed component 503, and a second previously formed component 504.
  • the first previously formed component 503 may be, for example, a phosphor lens and the second previously formed component 504 may be, for example, a diffuser lens.
  • a silicone optic 505 is subsequently extruded or molded over the existing optic. While not required, the illustrated silicone optic 505 may not be of consistent thickness but rather may have a high thick to thin ratio so as to better shape and control the light emitted from the optic.
  • the optic may be designed to emit light in a single direction or in multiple directions.
  • Moldable silicone typically does exhibit room temperature vulcanizing (RTV), meaning that by its nature it does not tend to stick or otherwise attach easily to other materials. Rather, mechanical retention may be necessary to attach some embodiments of the silicone optics disclosed herein to other structures.
  • structures or mechanical features such as voids (e.g ., grooves, holes, etc.) may be provided in an existing structure over which the silicone is molded so that the silicone fills the voids and, when cured, is mechanically interlocked with the existing structure.
  • Fig. 5 illustrates an embodiment in which grooves 502 are provided on one or both of the mounting brackets for this purpose and the silicone fills the grooves to interlock the silicone optic with the existing optic.
  • Components with multiple layers of differing materials as shown in Fig. 5 may be constructed on a rotary tool.
  • the optic 601 is formed with a reflector 602 or other element at least partially encapsulated within it, as shown in Figs. 6-9 .
  • a reflector 602 may be positioned in a mold and the silicone material cast or molded to form the desired optic 601 and so as to partially or entirely encapsulate the reflector 602.
  • apertures 603 extend through a portion of the reflector body. When the silicone is cast around the reflector 602, it fills such apertures 603 so that, when cured, the silicone optic 601 is mechanically interlocked to the reflector body. As shown in Figs.
  • the optic 601 may be extruded or cast/molded to include one or more recessed areas to at least partially surround an adjacent component.
  • the optics shown in Figs. 6-9 include a recessed area located near an adjacent component 604 where the adjacent component 604 may be one or more light sources.
  • Optic 601 typically may be up to 24 inches (61 cm) wide ( i.e., the transverse direction in Figs. 7 and 9 ) with a continuous length or any practical length ( i.e., the longitudinal direction in Figs. 6 and 8 ). Further, modular sizes may be from 1 to 12 inches (2.5 to 30 cm), 12 to 24 inches (30 to 61 cm), 24 to 48 inches (61 to 122 cm), and 48 inches (122 cm) or longer for continuous run luminaires.
  • FIG. 6-9 illustrate embodiments of the optic 601 provided with a mounting flange 605 or flanges that are partially encapsulated in the optic 601 but that include an exposed portion ( i.e., see mounting flange 605) that extends from the optic 601.
  • the exposed portion of the mounting flange 605 is provided with apertures 603 to receive mechanical fasteners for attaching the optic 601 to another structure.
  • each mounting flange 605 is shown formed integrally with a reflector 602 but such need not be the case. Moreover, in some embodiments, a reflector 602 is provided without a mounting flange 605 and in other embodiments a mounting flange 605 is provided without a reflector 602. Obviously many other types of mountings structures (e.g. , mounting brackets, etc.) can be molded directly into the optic 601 and used to attach the optic 601 to another structure. Embodiments are certainly not intended to be limited to the mounting flanges illustrated in the figures.
  • Silicone optics need not be formed only as linear optics. Rather, the present disclosure related to silicone or other materials may also be used in forming discrete lenses. It can be difficult to manufacture discrete lenses with the structure needed ( e.g., with the necessary thick to thin ratio, etc.) to achieve a desired optical distribution. In some embodiments, silicone may be used to enhance the optical properties of the lens.
  • Figs. 10-13 illustrate an embodiment of a round lens that has an optic shell of a first material 1001 (e.g., glass, plastic, etc. in the figures). The shell 1001 has a geometry ( e.g ., consistent thickness) that renders it easy to manufacture but that provides only generic light distribution.
  • a silicone optic 1002 may be used to enhance and customize that distribution.
  • silicone may be molded or cast on the outside or underside of the pre-formed optic shell to add shape to the lens so as to achieve the desired light distribution.
  • structures or mechanical features such as voids 1003 (e.g., grooves, holes, etc.) may be provided in the flange on the optic shell so that, when the silicone is molded or cast on the shell 1001, it fills the voids 1003 and thus mechanically interlocks the shell and silicone layers together with the first material 1001.
  • the shell 1001 may be formed of glass and the silicone optic 1002 may be molded on the underside of the glass directly over the light source 604 or internal to the luminaire such that the silicone is not exposed to the outside of the luminaire.
  • the outer shell of glass creates a clean smooth surface that is hard and resistant to scratching and other normal wear as well as dirt build-up.
  • the internal layer of silicone provides precise and sharp inner optical shapes with no draft ( i.e., taper with respect to a parting line) and some slight undercuts to control the optics to a higher level of optical efficiency over solid glass or plastic parts.
  • one or more grooves 1003 may be provided for the purpose of ensuring mechanical attachment between shell 1001 and silicone optic 1002 where the silicone fills the grooves to interlock the silicone optic 1002 with the existing optic shell 1001.
  • Silicone can be molded, cast, or extruded directly onto one or more first materials where the first materials are, for example, optical plastic grade acrylic poly(methyl methacrylate) (PMMA), polycarbonate (PC), or glass.
  • PMMA optical plastic grade acrylic poly(methyl methacrylate)
  • PC polycarbonate
  • the index of refraction is different for each material.
  • each pair of materials creates an internal surface at the interface of the different materials not visible to an unaided human eye.
  • the interstitial interface refracts light with fewer losses and, consequently, higher performance than if an air gap exists between materials.
  • the elimination of the air gap between materials ensures that losses are minimized because the elimination of the air gap causes more light to pass through the interstitial interface compared to light reflected in unwanted directions due to reflections created at the interface of a lens and an air gap.
  • the elimination of the air gap yields an increase in performance efficiency of 30% to 50% compared to known reflection losses with air to surface reflections.
  • the performance gains are due to (1) the interstitial interface and (2) the additional fine detail (small-scale features) of the silicone optical structure compared to glass.
  • the size and geometry of glass structure is limited due to the molding temperatures of glass which result in fine details breaking off during the cooling process. Further, glass requires steel tools, which, if built with the fine details seen in the silicone optics herein, will fracture in the molding process due to the high temperature of the molten glass.
  • the speed of light depends on the material properties of the object through which the light is travelling (i.e. , air, water, glass, plastic, etc.) and all materials have an index of refraction ( n ) to define the speed at which light passes through the respective material.
  • the angle of incidence i.e., the angle with respect to the normal direction of the surface of the object through which the light passes
  • the travel direction of light "bends" as it passes from a first material to a second material.
  • the amount of bending that occurs when the light enters the second material is proportional to the ratio of the indices of refraction of the first and second materials such that less bending will occur if the two materials have similar indices of refraction. Because, as described above, the interstitial interface eliminates any air gap between the silicone and the adjacent component to which it is bonded, the light bending that occurs is easier to control and calculate resulting in increased optical performance. For example, there is only one bending occurrence (lens-to-silicone) whereas a configuration with an air gap would result in two bending occurrences (lens-to-air and air-to-silicone). Furthermore, the materials can be selected to ensure similar indices of refraction to limit the amount of bending to better control and predict resultant light output and maximize efficiency.
  • a critical angle can be calculated for the interface between two known materials.
  • the light When light is incident on a surface of a material, the light can pass entirely through the material (either at the angle of incidence or at a refracted angle), part of the light can pass through the material and part of the light can be reflected at the surface, or, if the angle of incidence equals or is greater than the critical angle, all of the light can be reflected by the material (called total internal reflection or TIR).
  • the critical angle is the minimum threshold angle with respect to the axis normal to the surface of a material at which light incident on the material surface will be totally internally reflected by the material ( i.e ., will not pass through the material but be entirely reflected by the material). The exact value of the critical angle depends upon the material used for the optic and its index of refraction. Different combinations of materials have different critical angles.
  • Total internal reflection limits the degree to which light can be refracted or bent by an optic and thus limits the angular range at which light can exit an optic.
  • the hybrid optics described herein can be used to bend light more often and collectively to a greater extent than traditional optics to achieve light emission from the optic within a wider angular range. More specifically and as described above, the use of the interstitial interface allows two materials to be layered (without an air gap in between) such that light can be precisely controlled and provides three opportunities to bend the light including (1) geometric features at the entry surface of the first material, (2) the interstitial interface between the first material and the second material, and (3) geometric features at the exit surface of the second material.
  • the collective angle at which the light is refracted or bent by these three surfaces can exceed the critical angle while avoiding TIR.
  • additional layers can be added to the optic, which would increase the number of opportunities for bending of light.
  • lenses can be built that are capable of refracting light from any angle from 0° (parallel to the normal direction) to approximately 90° (perpendicular to the normal direction) including angles greater than the critical angle.
  • Co-molded optics can be made from any material suitable for optical transfer or reflection including but not limited to plastic, glass, silicone, metal, or film and can be bonded to a second material using a bonding substrate material to permanently adhere the optic structure to a second optical structure (constructed from the second material) to enhance optical properties.
  • FIG. 16 One example of an assembled light fixture including a place bonded silicone optic 1400 is shown in Fig. 16 .
  • the light source 604 is attached to a heat sink 1603 with an adjacent reflector 1602 such that light is directed into the pre-molded or pre-cast silicone optic 1400 before finally passing through the second material 1501.
  • the efficiency of the pre-molded or pre-cast silicone optic 1400 combined with reflector 1602 allows dimension H to be approximately 1 inch. Conventional light fixture arrangements often require approximately 6 inches for dimension H. Accordingly, the silicone optics described herein may help reduce weight, physical dimensions, and inefficiencies associated with traditional lighting fixtures.
  • a second material i.e., a sheet of glass
  • the costs associated with standard over mold tooling are high and such methods are time consuming because a tool must be designed and manufactured specifically for each application. From a business perspective, these methods are undesirable because it is difficult to amortize or recoup the cost of the tool during typical short life product runs.
  • the solution is to employ a method using a "place bonding" template die that is placed over the second material.
  • Pre-molded or pre-cast optics can be placed into the die openings by hand or using pick and place robotic system.
  • a heat cured silicone optical material is used to bond the pre-cast/pre-molded optic 1400 to the second material 1501.
